1. Kent Peterson's blog: http://kentsbike.blogspot.com/Kent is one of the most well-rounded and grounded blogging cyclists out there. People would do well to read and think about what Kent writes about.

2. Concur with "Jill Outside" blog...Jill is actually now in Los Altos, CA (San Jose/Bay Area), although Jill continues to write occasional stories of Alaska (like her most recent post) and always has great pictures!

3. Akuta-san's blog: http://www.symphonic-net.com/france1961/ (readers may wish to use a translator tool). I love the pictures of his rides throughout Japan. Akuta-san's photos of the food are awesome too!

Don't know whether my Bicycle Fixation counts as "non-commercial," as I once in a while post product announcements, but it is mostly about bicycle infrastructure and practice in urban areas, so maybe...?

Commerce occupies something like 2% of the website, including the blog, the rest being articles, essays, and pix of cyclingn & cyclists.

I like reading the blog of EG Square, a Moulton dealer in Nagoya, Japan. Sadly, improvements to Google's translation service have robbed us of most of the bizarre poetry of machine translation from Japanese, but still specialist bike porn a-gogo.

I'm very sad that Ecovelo has retired, that was my favorite bike blog. In a close second, is a tie with Lovely Bicycle and Lets Go Ride a Bike. LGRAB in particular is a great resource for new urban cyclists.

Also, I could just look at Rides a Bike for hours. It's a great daily pick-me-up.

This question is like asking about a favorite song, you think of ones you really like later on: but this one some might find interesting: Simply Bike Blog and I think she's a real nice person. At one point, I was under the impression she was up in Calgary but I could be wrong.

Italian Cycling Journal May not be the chosen lengua of this blog but it has a lot of entertaining tidbits, some of the high tech stuff I can do without but ever so often, something good and worthy of perusing with nice photos of the Dolomites, some history or whatever.
